Remarkable examples of \(\mathsf {RCD}(K,\infty )\)  spaces are pmGH-limits of Riemannian manifolds with Ricci curvature bounded below (the so-called Ricci limits ) [1]}, finite dimensional Alexandrov spaces [2]}, weighted Riemannian manifolds with \(\infty \) -Bakry-Émery Ricci curvature bounded below by \(K\)  [3]}, stratified spaces [4]}, (possibly singular) quotients of Riemannian manifolds with Ricci bounded below [5]}.
